Dominant Trait
The trait that is masked by a dominant trait, but CAN show up if another _________ is present (rr)
Recessive Trait
One dominant and one recessive allele (Yy, Ss, Rr, Bb)
Heterozygous
Two of the same allele (YY, yy, SS, ss) aka: two dominants or two recessives
Homozygous
The description of the trait in letters (BB means dominant blue eyes… “BB” is the ________)

Phenotype
Traits from your parents are shuffled so that you have an equal opportunity to get any traits from your parents
Law Of Independent Assortment
Traits from your parents are also separated so you only get one from each parent
Law Of Segregation
